JO URNAL-LUBRICATI'NG BOX.

SPECIFICATION forming part of Letters Patent No. 293,614, dated February 12', 1884.

Application filed August 30, 1881. Renewed August 16, 1883. (No model.)

T at whom it mag concern: I

Be it known that I, GEORGE F. SENTER, of the city, county, and State of New York,.have invented a new and useful Improvement in J ournal-Lubricating Boxes; and I hereby declare the following 'to be a full and clear description thereof.

This invention relates to a lubricating-box or box for containing and applying the lubricant to thcjournal in a continuous and uniform manner, without the use of waste,'wicking, or' other capillary conductor, such as is usually employed in car-axle journals and similar bearings. This invention relates, first, to the construction andcomposition of the lubricating-box;

and second, to the method or device for applying the box to the journal, so as to formacontinuous contact between the journal and the lubricant.

The invention will be readily understood by reference to the accompanyingdrawings, of

which' Figure 1 is a longitudinal sectional elevation of the improved lubricating-box, as ap plied to the journal of arailway-car axle. Fig. 2 is a transverse sectional elevation of the same. Fig. 3 is a front elevation of one car-wheel axle with its wheel and bearing-box and pedestal, and also showing thelubricating-box in place.

The axle A, the bearing-box B, and the pedestal O are such as are in use now or in anywise adapted to the purpose indicated. These other axle.

This box or shell D, I form of. a soft anti-friction material, which may be pressed hard against the journal-bearing without producing any deleterious friction between the parts. The material for this purpose may be any sufficiently firm anti-friction material; but I prefer to use for the purpose a mixture of lead, antimony, and ground plumbago, melted to gether, and cast in the form required. These I metals may be united in about equal proportions; but this is not a matter of importance.

with a steady though yielding pressure by means of the spring E, so as to cause the said box Dto constantly contact with the journal, thereby keeping out all dust anddirt from the bearing, and also causing the ends of the box D, which press against'the journal, to slowly wear away, thereby permitting the lubricant journal. v

Itwill beseen that the box D, made of an anti-friction material, and soft enough to easily though slowly wear away, will not add to the frictional resistance on the journal, but in many places will be of sufficient firmness to act as the cap of the journal-box, and at all times will hold the lubricant up to contact unused lubricant to be constantly set up to and in contact with the journal, the springs E, as before explained, acting to constantly press'the box up to the journal. The spring or springs E (there may be one or more of them) will preferably be spiral springs, though any form of spring will of course answer the purpose, and these springs will act against a'basepl-ate, E, so as to constantly press the box 'D and its contents against the journal. The base-plate E will rest against the base-plate of I thepedestal, or against any suitable stationary or relaarrangement of the lubricating-box, cotton or other waste or fibrous capillary conductor for the oil or lubricant will be wholly dispensed with. The journal will be almost entirely covered, and thereby dust excluded effectually from the journal, and consequently the wear on the journal and its box will be greatly reduced.

These lubricating-boxes may of course be placed at the bottom of the journal, as in the case of a car-axle, as shown in the drawings,

quired.

Having described my invention, I claim 1. Ahollowlubricating-box adapted to contain a stiff plastic or semi-solid lubricant, provided with a longitudinal opening in the side next the journal, wherebythe body or mass of This box I press. against the journal-bearing tively stationary part of the bearing. By this D to be brought in constant contact with the 1 with the journal, as the slowly-wearing-away contacting surfaces of the boxD will allow the or in any other position which may be re- IOO 3. The combination of the slotted pedestal G, the bearing-box B, the axle A, the rectangular hollow lubricating-box D, constructed of soft anti-friction metal, and provided with a longitudinal opening in its upper side, the semi-solid lubricant D,contained in said box, the spring E, and plate E, all substantially as described.

GEORGE F. SENTER.
